As shown in Table 1, beneficiation opportunities, i.e., metals/minerals recovery, are available for both effluents and particularly for AMD. However, radionuclides might also be present in drainage that originates from gold mining, but these are rarely found in coal mine drainage (Tutu et al., 2008).

Use of NaHS and silver ions has been reported to improve gold recovery at the Los Pelambres mine in Chile (Chryssoulis 2001 ). Sulfide ions appear to act as flotation activators at low concentrations less than 10 −5 M, whereas at concentration above 10 −5 M, it acts as a depressant (Aksoy and Yarar 1989 ).

Gold placer mining consists of three major operational steps: extraction, beneficiation and processing. Extraction is defined as removing ore material from a deposit and encompasses all activities prior to beneficiation. Beneficiation is the operation by which gold particles are separated from the associated undesirable material.
